NEW PRODUCTS
Updated PFAS Solution/Mixtures for U.S. EPA Methods
Multiple U.S. EPA methods commonly used for the analysis of PFAS (e.g. 533, 537.1, and 8327)
recommend quantitative standards containing mixtures of branched and linear isomers due toobserved differences in ion response. To aid in the analysis of these compounds, Wellington has
updated our current selection of mixed PFAS reference standards to include EPA-533APDS, EPA537APDS, and EPA-8327STK. These solution/mixtures contain previously unavailable quantitative
isomeric mixtures of PFOA and PFNA, as well as FOSA for EPA-8327STK, but are otherwise identicalto our existing EPA-533PAR, EPA-537PDS-R1, and PFAC-24PAR products, respectively.
